Sunflowers are not toxic to cats. According to the American Society for the Prevention of Cruelty to Animals (ASPCA), sunflowers are listed as non-toxic to cats. If a cat nibbles on sunflower petals or leaves, it generally does not pose a serious health threat. However, some cats might experience mild digestive upset such as nausea, vomiting, or diarrhea if they eat a large amount. Sunflower seeds themselves are not toxic either, but salted or seasoned seeds should be avoided as salt can be harmful to cats. The hard shells of sunflower seeds could also pose a choking hazard or cause internal injury if ingested. Sunflower oil is safe in small amounts but overconsumption can lead to digestive issues and obesity in cats. Overall, while sunflowers and their seeds (without shells or salt) are safe for cats, it is best to limit their intake to avoid any mild stomach upset.
